That's the one.
Here some more I liked.
The SAS Combat Handbook: Amazon.ca: Jon E. Lewis: Books
Get the whole serie of books... I got 2 of them and they are all good.
Light Infantry Tactics: For Small Teams: Amazon.ca: Christopher E. Larsen: Books
Best tactical handbook for feild use I've read. Simple, no bullshit. Photos to explain, graphics. Well written, Usefull for airsoft. You can't command a small team without reading this book first. You could... but you'd fail.
That's it for now.
